The Sigma was great. No argument with its optical performance. Its just that it was a bigger heavier lens and f4.0. With a Speed Booster it became and f2.8 obviously but that made it bigger, longer and heavier. For most of my work I found the 28-75 Tamron to be the one I often picked up for use on both the FS7 and the A7III. Also if on a gimbal the weight and the shorter lens extension make it easier to balance. Combine that with more accurate AF on the Sony it makes for a better choice than the Sigma in my book. Basically the AF performance displayed by David Oastler in the following vids is something I would agree with.why did you sell the sigma 24-105, Chris? And is it possible that tamron AF performance on sony is exceptional?
